通过对SQL Server 2000分布式功能和机制的分析研究,给出实现SQL Server 2000分布式数据库系统的逻辑架构.介绍了SQL Server 2000服务器注册和构建链接服务器的步骤,讨论了SQL Server 2000数据库分布存储的数据分区概念、分区设计和实现,以及分布式分区视图的创建及其在分布式查询中的应用.
Based on the analysis of the task sizes and the load, this paper discussps the granularity ofrelation spliting in the spliting phase taking acount of task load being less than average load,andprobes into the relationship between the granularity and load balancing. The minimum number ofbuckets is determined on the basis of relation spliting granularity,and the maximum number ofproduct tuples of each node is induced under the prerequisite for ensuring load balance in paralleljoin.
